Cherry angioma is a cherry-red to purple colored benign skin tumor of unknown origin that appears most frequently after age 40. They are the most common vascular lesions to appear on human skin. They are made up of clusters of dilated capillaries on the surface of the skin, which accounts for the cherry-red or purple color. No one knows exactly what causes them. They can occur almost anywhere on the skin, but most commonly on the torso. They rarely occur on the hands or feet. When they first occur, cherry angiomas are about the size of a pinhead and do not protrude above the surface of the skin. However, some grow to 1/4 inch across or more, and become spongy and dome- or mushroom-shaped.
